Description: |
| J. H. Adams - patent attorney
The object of my invention is to construct a tool-post for lathes, planing-machines, &e., in such a manner as to enable the point of the cutting-tool to be readily adjusted in any desired position relatively to the material to be operated upon and the invention consists in attaching the tool-post to the base-plate by means of a ball and socket joint, in combination with a collar, fitting upon the outer surface of the socket portion, thus forming a double bearing. Upon the collar is supported the cutting-tool, which passes through a slot in the upper portion of the post, and is held in position by means of a screw passing through the top of the post in the usual manner.
